Abstract

The vacuum pump (12) or vacuum device has two suction inlets (13,15) with multiple pressure stages. An outer suction inlet for one pressure stage spatially encompasses an inner suction inlet for another pressure stage such that the inner suction inlet seals only against pressure within the outer suction inlet and not against external pressure. Two volumes are provided different pressures and the two suction inlets of the vacuum pump are connected to the volumes of different pressures. An independent claim is also included for evacuating a vacuum chamber with multiple volumes and pressure stages.
